CSF Examined for Enteroviral Nervous System Infection

Infections caused by enteroviruses are among the most common infectious diseases of the central nervous system (CNS). Enterovirus infections account for 40-77% of all viral meningitis cases in adults. An infection of the meninges results in an uncharacteristic headache usually accompanied by fever and neck stiffness. More...

TB-LAMP Assay Evaluated in Reference Labs

Smear microscopy, the first line in tuberculosis (TB) detection, has a low and variable sensitivity of 30% to 70%. Conventional culture on solid media has a sensitivity of 80% to 90%, but requires two to eight weeks for a result. More...

Blood Test Predicts Onset of TB in Advance

Tuberculosis, caused by infection with Mycobacterium tuberculosis (TB), is the world's leading cause of death brought on by a single pathogen. More than 10 million new cases of TB are diagnosed each year, and almost two million people die from the disease. More...

New POC Test Quickly Detects Lyme Neuroborreliosis

The clinical pictures of borreliosis vary from local skin infection to infections of the central nervous system, joints or the heart. A typical red rash, the so-called erythema migrans lesion, developing and spreading around the tick bite should always be treated with antibiotics without laboratory tests. More...

Immunoassay Developed for Lassa Fever Virus

Lassa fever is a type of viral hemorrhagic fever and is endemic in several West African countries. However, only few hospitals and laboratories in the region have the capacity to conduct molecular or serological Lassa fever diagnostics. More...
